To all whom z't may concer:

Be] it known that I, JEssE A. B. SMITH, a

citizen of the United States, residing in,

Stamford, in the county of Fairfield and State of Connecticut, haveinvented certain new and useful Improvements in Type- VVriting Machines,of which the following is a specification.

This invention relates to an improvement in typewriting machines, andmore particularly to an attachment of the fan-fold type, but in whichthe work-sheets are on separate strips, and is an improvement on myapplication No. 165,055,filed April 28, 1917, and iatent to Lester A.Wernery and Jesse A. i3. Smith, No. 1,132,055, dated March 16, 1915.

The present improvement is applied to an lattachment for typewritingmachines whereby a number of copies of' the same piece of work can besimultaneously Written, and a large number of pieces of work producedsuccessively by the interleaving of carbon sheets with continuous stripsor webs of work-sheets. The carbon sheets are repeatedly used and thework-sheet strips spaced relatively to them for each new piece of work.

To effect the spacing between the worksheet strips and the carbonsheets, the platen is swung up out of its normal typewriting position soas to straighten out the bend in the pack of interleaved carbon andworksheets. In this way, the friction is reduced so that the work-sheetcan be shifted relatively to the carbon sheets, and vice versa.

Where the worksheet strips are separate, as in the present invention,there is attendency of the sheets to creep relatively to one another,due to the folding and unfolding around the platen. Provision istherefore inade in the `present invention for enabling the sheets, whenthey are spaced for each new piece of tyoewritten work, to. be justi`fied or re-registered relatively tri-.one another, thereby preventingthe creeping from being cumulative.

For this purpose, there are provided two or more studs which cooperatewith perforations provided in the side margins of the These perforationsmayL be used for assemblin the completed s eets later in loose-leafEooks, if desired. The studs are normally retired 'lor moved to anon-projecting ppsition, so that when the sheets are fed around theplaten for typewriting the studs will not interfere with the line-feedmovements of the paper. When, however, the platen is raised toa/fposition to take out the bend or Warp in the pack of assembledsheets, then .'the studs a automatically projected to gaging positions,so that the work-sheets can be strung thereon. Then, when the platen isreturned to its noi'- mal position, the studs are automatically recededto a non obstructing position, the

sheets being then under the control of the' usual feed rolls. Theautomatic projection and recession of the collating or aging studs arepreferably controlled by te swinging ofthe platen from a normaltypewriting ,position to a collating position and back again.

Other features and advantages will hereinafter appear.

Referring to the drawings,

Figure 1 is a perspective View, partly broken away, to show theunderlying structure, and illustratin the platen in its normaltypewriting position, with the pack of assembled work and carbon sheetswra ped around the same, as shown in dash-an -dot lines.

Fig. 2 is a side` view in elevation, with parts broken away to show theunderlying structure, and the platen in the Same posisheets withdrawnrearwardly from the platen,

enabling the forward spacing of the worksheets relatively to the carbonsheets. The

gaging or registering studs are shown in their projectin positions,which are coincident with the e evated position of the platen.

Referring more particularlyv to the se arate parts of the device, `1indicates t e platen, which is secured'to a platen axle 2, mounted on anauxiliary frame. 3, within the usual platen frame 4. The auxiliary frame3 has a pivotal mounting by means of a rod 5 on the platen frame 4, sothat it can be swung from the position of Figs. 1 and 2 to the positionof'xFig. 8. This is for the purpose of relative rif-adjustment of thework-sheets and carbon sheets in a manner more fully describedhereinafter.

The usual lever (3 is provided for effecting line-hy-line feedingmovements of the platen 1. The line-space lever 6 is provided with anarm 7, which engages theusual slide 8, havin an adjustable line-spacedog, (not showiil, which engages at the proper time a ratchet wheel 9,secured to an axle 10,oarry ing the usual knob 1l, whereby the platen isordinarily spaced back or forth several lines at atime.

ln order to allow for the movement be-r tween the axle 10 and the axle.2, which are in al'inement with each other, but separate, a specialgearing is provided in said patent. There is secured onv the axle 10 agear 12, which take-.s all the movements of the axle 10, due to theline-spaoe lever 6 and the knob l1. The geur 12 meshes with a broadpinion I3, which also overlaps a gear 14 of the same diameter as thegear 12, but seem-ed .to the axle In this Way, the movements of thelinespaee lever (i and (he knob l1 are transmitted to the platen I. Thepinion 13 is concentric with therod 5, about which the platen .swings asa center, so that there is Aio break in the driving train when theplaten is moved between typewriting and re-registering positions.

To swing'the platen 1, there is provlded u hand-crank 16, secured to theswinging iframe 3. rThe swinging frame end the handrrank 16 are normallyheld in a types` writing position of the platen'hy a latch 17, whichengages a pin 18, provided on the hand-crank 16.

The morir-sheets, which, in the present inventirm, are preferably inseparate strips, coming from separate rolls or from a` loose parli,v(not shown). extend 'from a point somewhat in the reni' of the platen.The worksheets, indicated by the reference numeral 19, extend over aguide 'frame 20, which is secured to the platen frame 4, so as to travelwith the carriage in a letterspacingdireetion. This frame 20, issupported at its rear end. by e roller 2l., riding on. a. rail 22,carried by a pair of brackets Q3, mounted on the frame of thetypewriting;V machine or other suitable support.

The carbon Sheetgindicated at 24, of which there are two shown, aresupported so as to he interleaved between the worksheets 19. For `thispurpose, there ispro vided a traveling table 25, having a movementtoward the platen to keep pace with` the advance of the sheets aroundthe platen. The table .25 is provided with rollers or wheels 26, whichtravel in tracks 27, provided by the side rails of the frame 20. Ex-

tending alternately, inwardly fromy the frameQO from the sides of thetraveling table 25, are supporting arms 28 and 29 for the carbon sheets9A. The inner ends of these arms are free, so that the looped ends ofthe carbon sheets 24 may be slipped onto the arms 28 und 29. Il moreworksheets than three are used, more carhons may lie-670 1, Where theusual typ-.liars 36 strike the i platen. From this point, the assembledwork and carbon sheets pass up onto a registering taille or board Iii".which serves also as :t guide. The registering table may he provided atits right-hond side` with e slidable side gage wij. which may beadjusted lengthwise of the i. istering table for worksheets of differentWidths.

At theleft-hand side of the registering table 37, there are provided twoor more openings 39, corresponding to perforations 40,provided in thework-sheet strips 19. These perforations may be used for assembling theseparated pieces of work later in loodeaf hooks, if desired. They arealso used forkadjusting the several strips rela tively to eachother fromtime to time, so that the aline-ment of `the different sheets with eachother muy be aeeurate. This is necessary in eases where the work-sheetstrips 19 eaeh are. com osed of continuous repetitions of forms ofpeomesort` or other, and it is desired that certain portions of each formaline prorly with each other,

so that metter may in he proper place. The registeringie le B'is=oxzended at 41 to allow foruone of the openingsBQ and othermechanikmto be now described.` The openings 39.`n the registering?trahie 37 are for the purpose, of permitting et ds 43 to be shifted rome normal, rede position, shown in Figs. 1: and Q, to a. proi im )ectedposition, shown in- Fig. 3. 'Iheistuds 43 are mountedon a block 44,Which,at.Fi

This' tendency is opposed by a. rod4S, en aging a ca'm 49, provided on the slide. he/rod 4851s, securedto', the fixed portion of the plalniframe 4.
